I have used X-10 for many, many years. About 6 months ago I went wi-fi and cell phone apps and I love it. We still have several 16ch remotes in various locations throughout our home for manual control. I have the active phase coupler wired into my main power panel. I also have 3ch stick on wall plates and a single wireless receiver to accommodate the wireless. I used to try to use a lot of wireless remotes but got really frustrated with it not being reliable. The wi-fi seems to have solved my problems, until now. I have 1ch that has decided to not respond to the wi-fi apps and even some of the hardwired remotes in different locations in my house. I tried re-addressing those dimmers with no luck. This feels like the same old problems I used to have and that is poor communication between phases. I have trudged through this kind of problem before until I installed the wi-fi. The wi-fi seems to have much improved signal strength and has worked perfectly for about 6 months. FYI, I have 22 different modules. Some are relays, some wall dimmers, some plug-in modules, some slow fade and some instant on and some three-way. Lot's of X-10. My next step is to take the cover off of my panel and re-wire the non working modules to the other phase. I'm guessing that may solve the problem but I'm thinking why should I have to do this with the phase coupler. The ch in question is two separate plug in dimmer modules set for same channel and rated @ 300 watts ea. Both lamps are LED. Before anyone says LED is the problem remember that this circuit worked great for 6 months and just a couple of lamps in my home are incandescent and the rest of my house is LED. By the way, the "warm glow" lamps seem to work well with the X-10 triac dimmers. Certain LED array types work better than others. Extraneous noises on the power line as from capacitor start ac units and other electrical occurrences seem to impact X-10 control but the wi-fi has been very strong and we just have this one circuit that doesn't respond, except every now and then.
I would love to hear some suggestions.
Thanks much
